Abstract
The present discloses an ion sensor and its readout circuit. The sensor includes potentiometric, amperometric ion sensors or dual mode electrochemical sensor. The dual mode electrochemical sensors can be measured by the same measurement circuit system. The dual mode sensors are extended gate ion sensitive field effect transistors and amperometric biosensors. The measurement circuit system is adaptable to the different mode sensors.
